    Anybody recognize this problem in any text books?

    JohnRwals (Structural), Thank you for your response. I appreciate it. However, I didnt find this in "Vector Mechanics for Engineers". If by the chance you seen it there I appreciate stating the edition and chapter that you found it there. To all, I appreciate your interest in expressing your...

    Anybody recognize this problem in any text books?

    Hello All I am curious if any of you recognize what text book this figure you may have seen? I greatly appreciate it if you recognize this figure and recall what book you may have seen it. Respectfully, Sk...

    Strain gauge experience

    SWComposites Thanks for your question but does it matter where we are going to use the strain data???

    Strain gauge experience

    Also, I would like to know how many strain gauges we need for an element under pure TORSION?

    Strain gauge experience

    Does anybody know for an element in tension only or say pure tension how many strain gages do I need on the element? One, two, four??? Thank you

    Solution Manual- Harry West -Fundamental of Structural Analysis

    I just like to know partial solution to one of the practice problems for my education. I dont mean any copyright violation or anything else. I thought a partial solution to just one practice problem is not a big deal!!! My apology for asking then .

    A Dynamics question

    If anybody can help me with the solution of this problem, I would greatly appreciate it Please see attached Thanks My Engineering Mechanics/Dynamic is rusty https://files.engineering.com/getfile.aspx?folder=c26fc894-477d-461c-b572-0cd6bce0b269&file=Mac.JPG

    Concrete Brain teaser question

    Does the pour direction of concrete affect the strength of concrete If two concrete elements one poured vertically and the other poured horizontally will one be more stronger?

    Degree of indeterminacy

    The frame elements with EI are rigid connection to each. The frame is pin supported on ground at each supports. Cable is pined at each end to the frame. Hope I am clear stating the problem. However, confused as hell ...

    Degree of indeterminacy

    So my understanding from your replays is : The questioned frame which has both of its supports as hinges or pinned and none are rollers. Regardless of the applied load (P) as shown on the frame including the diagonal cable, the system is one degree indeterminate as r13 response. However if the...

    Degree of indeterminacy

    What if the right support was a roller instead, would then you call it a determinate system?

    Degree of indeterminacy

    Tomfh, Thank you for your response too. r13, dont mean to bug you so much but cant follow your instruction. The frame itself has rigid joints. The frame without the cable is one degree indeterminate (Do you agree with that?) Then cable ad one more unknown which makes it total of 2, doesnt it...

    Degree of indeterminacy

    r13 (Civil/Environmental) Thank you for your response but how do you come with one? I came up with 2 and my reason is the structure frame is one degree indeterminate (due to having pin supports) and force in the cable will be another unknow so it makes it in total 2 degree indeterminate. Where...

    Degree of indeterminacy

    I like to get some opinions on the correct degree of indeterminacy of below frame? Thank you

    Principle stress trajectory of beams

    r13 (Civil/Environmental) I am sorry I couldn't understand your last post on your best guess! I see some red arrows, may I ask what are they representing? Can you please explain a bit in details whats your "guess work"?

    Principle stress trajectory of beams

    r13 (Civil/Environmental), I would like to thank you so much for your kind effort trying to help me. Greatly appreciate it. I agree that the curve contours are the right answer for the principle stress and I heard you mentioned the straight line is for zero shear9pure bending), however in a...

    Principle stress trajectory of beams

    Anybody else can help please regarding the two figures or stress trajectory for a cantilever beam with a point load at the free end? Which one is a correct and why? I am struggling to find what is the straight lines in the first figure? I appreciate it you seen it in any reference book or text...

    Principle stress trajectory of beams

    r13 (Civil/Environmental) Many thanks for response. My apology for bugging you but if you possibly remember where you might have seen it that would be great help. I dug all my strength of material books and did not find this. If by the chance you recall what book may have address it, I would be...

    Principle stress trajectory of beams

    r13 (Civil/Environmental) Thank you for your response can you please explain little in details what's the first one? Major shear stressed? Never heard of major shear stress!!! Just we had principle normal stresses didnt we? Is major shear stress the Tau at each point? Where can I learn on...
